When using steel ball bearing hinges shall comply with the technical requirements of GB / T 699-1999 and GB / T 700-2006 of the relevant provisions. Ball bearing hinge castings when using multi-directional movable ball joint bearing manufacturers, their chemical composition, mechanical properties after heat treatment and after heat treatment and mechanical properties and impact toughness comply with the relevant provisions, meanwhile, cast steel ball bearing hinges members should meet the following requirements; castings after machining, ball joint bearing surfaces and the presence of casting defects appear not allowed when using the premiere and performance, allowing the repair, once more than the specified defects and cracks appeared not allowed etc. shall not be used and the repair of steel castings. Steel castings before welding, clearly showing the defect treatment should be good until the double entry movable metal ball bearing hinge prices and 30mm distance within the range of bevel edge and bevel surface is clean, simple and honest To which grinding to comply casting surface quality requirements, and shall have not welding. Crack, the ball bearing slag hinge holes and other defects, pots and bottom welded ring up does not affect its mechanical properties. Cast steel castings required according to the provisions of ultrasonic visits, ball joints and bearings should reach cast requirements and internal cracks are not allowed. Brass is a raw material used in ball joint seal bearing, bearing Uno General brass two-way movable ball joint bearing manufacturers, ball bearing hinge its mechanical properties and chemical composition of indicators should be specified. Ball bearing hinges are developed on the basis on the basis of the pot bearing initiated on a ball joint mount, back in the 1970s, it developed into a foreign spherical seat, in 1988 China has also started to develop a spherical support seat and started for engineering practice, complete the national standard setting work in 2000, the spherical bearing not only involve adapt the scope of the corner and carrying capacity than ball joints are bearing large, so, enter the 1990s, spherical bearings China's large-span bridges in the project has been more widely used, and completed the revision of the national standard in 2008, while the completion of the core standard package involves the design drawings. General construction spherical bearing, ball bearing hinge by the bearing plate, spherical steel liner plate, the ball bearing slide hinge plane Teflon skateboards, skateboard spherical PTFE, seals and dust cover, etc. parts do, whose main components constructed spherical seat role and requirements. Ball bearing hinge plate can also be called a bottom basin movable ball joint bearing, usually made of steel castings, bearings also useful for small tonnage situation thick steel processed, mainly from the lower bearing plate fixed spherical PTFE plate of the role and support reaction force is transmitted to disperse or bridge piers supporting the platform. Ball bearing hinge rotates by sliding spherical steel liner plate between the spherical PTFE plate to achieve, but usually spherical steel liner plate steel castings finishing, ball bearings and spherical hinge processing completed Now there are cases using coated stainless steel surfaces. If after using steel processing, machining precision sphere will refer directly affect the function of bearing rotation, which points to attract attention.
